D. Paper feed direction
When the direction in which paper is fed is in parallel with the longer side of paper, the
paper feed direction like this is referred to as the longitudinal feed.
And the paper feed direction that is perpendicular to the longitudinal feed is referred to as
the transverse feed.
When specifying the longitudinal feed, "S (abbreviation for Short Edge Feeding)" is added
to the paper size. For the transverse feed, no specific notation is employed.
However, when only the longitudinal feed is specified for one and the same paper size with
no specification made for the transverse feed, "S" is not added even when being fed longi-
tudinally.
